If you feel as though you are in danger of harming someone, I'd seek help. What kind of help exactly? I'm not really sure as I don't know what works best for you. Just because you've not acted on these feelings and impulses yet doesn't mean you won't sometime in the future. I'd nip it in the bud before someone gets hurt. If that happens, you'll have a lot more to worry about than what your dealing with now.
